Ejector for electrical connector

Abstract

A manually actuated ejector for electrical connectors for providing an initial disconnection movement between connector components includes a pivotal lever attached to one connector component having an actuator link connected thereto, the link terminating in a connection to a rotatable cam carried by the one connector part with a cam face in juxtaposition to an opposed surface of a second connector part whereby movement of the lever rotates the cam in opposition to the second connector part causing relative disconnection movement between the two connector parts.

We claim:  
     
       1. An ejector assembly for electrical connectors for urging mating connectors bodies apart comprising a connector housing, a lever pivotally attached to the connector housing, a link attached to the lever spaced from the pivotal attachment to the housing, a cam pivotally attached to the housing at a point spaced from the lever attachment, said link positioned exterior of the housing, the link having an attachment to the cam whereby upon movement of the lever the cam is rotated. 
     
     
       2. A device according to  claim 1  wherein the cam is positioned on the housing such that a face of the cam providing a cam surface will be adjacent to or in contact with an opposed surface of a mating complimentary connector body when the connector housing and complimentary connector body are in fully seated connection. 
     
     
       3. An electrical connector assembly comprising first and second members adapted to be connected together, a face on the second member, a cam pivotally attached to an exterior surface of the first member at a pivot point and having a cam face opposed to the second member's face when the members are operatively positioned together, the cam rotatable with respect to the first member about the pivot point and having a cam face configuration which changes the distance between the pivot point and the point of cam face contact with the second member's face during rotation of the cam whereby rotation of the cam in one direction will force the second member's face away from the pivot point thereby separating the connectable members, an actuating lever for causing movement of the cam, the lever pivotally carried by the first member at a point spaced from the pivot point, and means connecting the cam to the lever. 
     
     
       4. A device according to  claim 3  wherein two cams are provided on the first member each having camming faces contactable with the second member's faces. 
     
     
       5. A device according to  claim 4  wherein the means includes a link connection between the pivotal lever and the cams for causing simultaneous rotation of the cams.
